Definitions

  • the present invention relates to a cutting insert, a cutting tool, and a method of manufacturing a machined product using the same.
  • a minor cutting edge having a larger peripheral cutting edge angle than the major cutting edge is formed between the major cutting edge and the flat cutting edge from the viewpoint of damage reduction of a cutting edge.
  • Japanese Unexamined Patent Publication No. 2008-544872 discloses a cutting insert in which the angle formed between a major cutting edge and a flat cutting edge is 45°, and an intermediate cutting edge 11 (minor cutting edge) having a larger peripheral cutting edge angle than the major cutting edge is formed between the major cutting edge and the flat cutting edge.
  • the chips generated from the individual cutting edges flow differently at a boundary of the major cutting edge and the minor cutting edge. Therefore, the chips might be twisted, and it might be difficult to perform chip treatment.
  • An object of the present invention is to provide a cutting insert, particularly a negative type cutting insert having excellent chip discharge performance, a cutting tool, and a method of manufacturing a machined product using the same.
  • a cutting insert includes an upper surface; a lower surface; a side surface connected to the upper surface and the lower surface; and a cutting edge which is located along an intersection of the upper surface and the side surface, and includes a major cutting edge, a flat cutting edge, and a minor cutting edge located between the major cutting edge and the flat cutting edge.
  • the upper surface includes a flat part which is located away from the cutting edge and is perpendicular to a central axis of the cutting insert, and a rake face inclined downward from the cutting edge to the flat part. In at least a part between the major cutting edge and the flat part, a groove part lies along the major cutting edge.
  • the groove part includes the rake face and a rising face which is inclined upward from the rake face to the flat part and connects the rake face and the flat part.
  • a cutting tool includes the cutting insert and a holder configured to attach the cutting insert thereto.
  • a method of manufacturing a machined product includes rotating the cutting tool; bringing the cutting edge of the rotating cutting tool into contact with a surface of a workpiece; and separating the cutting tool from the workpiece.
  • connection part where the rake face and the flat part exist continuously extends from the minor cutting edge to the boundary of the minor cutting edge and the major cutting edge, and the specific groove part is disposed on the upper surface along the major cutting edge. Therefore, the cutting insert performs a satisfactory chip treatment for a wide range of chip sizes.
  • the small width chips susceptible to twisting which are generated when the amount of depth of cut is small, namely, when only the minor cutting edge is used, or when the vicinity of the boundary of the minor cutting edge and the major cutting edge is used mainly, can be curled while reducing twisting, by the region where the rake face and the flat part exist continuously.
  • the large width chips less susceptible to twisting which are generated when the amount of depth of cut is large, namely, when the major cutting edge is used mainly, can be curled by stabilizing the chip flow by the corresponding groove part.
  • the insert 1 includes a body part of a substantially polygonal plate shape. No particular limitation is imposed on the shape of the body part. That is, the body part may have a certain shape usually employed by those skilled in the art, such as triangle, quadrangle, pentagon, hexagon, and octagon in a top view.
  • the present embodiment employs a substantially pentagonal shape having five long sides.
  • the insert size may be suitably set depending on cutting conditions. For example, the length of one side is 8-12 mm, and the thickness is 4-8 mm.
  • the body part also includes an upper surface 2, a part of which functions as a rake face; a lower surface 3, a part of which functions as a seating face; and a side surface 4 which is continuous with the upper surface 2 and the lower surface 3, and functions as a flank face.
  • Cutting edges 5 are respectively formed along the intersection of the upper surface 2 and the side surface 4.
  • the upper surface 2 includes flat parts 6, each of which is spaced away from the cutting edge 5.
  • the term "flat part” denotes the flat part located away from the cutting edge on the upper surface.
  • the flat part may be made up of a plurality of flat portions of different heights.
  • the flat part 6 includes a high position flat portion 61 and a low position flat portion 62 located at a lower position than the high position flat portion 61.
  • the terms "high position” and “low position” denote positional relationships in a direction perpendicular to a flat surface when the lower surface is left to stand on the flat surface.
  • the flat part 6 is provided with an attachment screw contact part 7 extending through the body part from the upper surface 2 to the lower surface 3.
  • the attachment screw contact part 7 is disposed at a central part surrounded by the flat parts 6.
  • the side surface 4 is perpendicularly connected to the upper surface 2 and the lower surface 3. That is, the insert 1 is a negative type insert allowing both the upper surface 2 and the lower surface 3 to be used as the rake face. Therefore, the insert 1 is the insert whose ten corners are usable.
  • the cutting edge 5 is also formed along an intersection of the lower surface 3 and the side surface 4.
  • the lower surface 3 also includes the flat part 6 (not shown) spaced away from the cutting edge 5.
  • the insert of the present invention may be a so-called positive type insert in which a clearance angle is imparted to the side surface 4.
  • the cutting edge 5 formed along the intersection of the upper surface 2 and the side surface 4 includes a major cutting edge 51, a flat cutting edge 52, and a minor cutting edge 53 disposed between the major cutting edge 51 and the flat cutting edge 52. Further in the present embodiment, as shown in Fig. 2(a) and 3 , a first corner cutting edge 54 is formed between the major cutting edge 51 and the minor cutting edge 53, and a second corner cutting edge 55 is formed between the minor cutting edge 53 and the flat cutting edge 52.

  • the major cutting edge 51 is configured to be the longest among the cutting edges 5 (51-55).
  • the major cutting edge 51 may have a linear shape or curved shape (arcuate shape) in a top view. It is suitable for the major cutting edge 51 to have a positive axial rake with respect to the rotation center axis of a holder when attaching to the holder. Hence, the major cutting edge 51 is preferably inclined downward away from the minor cutting edges 53 adjacent to each other in a side view, as shown in Fig. 2(b) .
  • the term "downward” denotes a concept indicating a direction from the upper surface to the lower surface of the insert with respect to a plane orthogonal to the center axis of the insert.
  • the major cutting edge 51 has the linear shape in the top view as shown in Figs. 1 and 2(a) .
  • the major cutting edge 51 has a concave shape toward the lower surface 3, and a straight line connecting both ends thereof is inclined with respect to the lower surface 3 in the side view as shown in Fig. 2(b) .
  • This allows the major cutting edge 51 of the insert 1 to be attached to the holder so as to have a positive axial rake.
  • the major cutting edge 51 may be provided with a groove part that divides the major cutting edge 51.
  • the major cutting edge 51 is located at a higher position than the flat part 6 as shown in Fig. 4(a) . This reduces contacts between the chips after passing through the rake face 56, and the flat part 6, thereby achieving efficient discharge.
  • the flat cutting edge 52 is formed for improving the surface finish roughness of a workpiece.
  • the flat cutting edge 52 has a linear shape in the top view as shown in Figs. 1 and 2(a) , and is inclined upward toward the minor cutting edge 53 in the side view as shown in Fig. 2(b) .
  • the term "upward” denotes a concept indicating a direction from the lower surface to the upper surface of the insert with respect to the plane orthogonal to the center axis of the insert.

  • peripheral cutting edge angle means an inclination angle of the cutting edge with respect to the rotation center axis of the holder when the insert is attached to the holder.
  • the peripheral cutting edge angle of the major cutting edge 51 can be expressed by an angle ⁇ formed between a line L parallel to the rotation center axis of the holder, and the major cutting edge 51 in a top view.
  • the peripheral cutting edge angle of the minor cutting edge 53 can be expressed by an angle ⁇ formed between the line L and the minor cutting edge 53.

  • the minor cutting edge 53 preferably has such an inclination angle as to have a positive axial rake with the insert 1 attached to the holder.
  • the minor cutting edge 53 is located at a higher position than the flat part 6. This reduces contacts between the chips after passing through the rake face 56, and the flat part 6, thereby achieving efficient discharge.

This reduces large thickness variation among chips respectively generated from the major cutting edge 51 and the minor cutting edge 53, thus permitting shape control of the chips.
  • the first corner cutting edge 54 and the second corner cutting edge 55 may be linearly chamfered.
  • the upper surface 2 further includes a rake face 56 inclined downward from the cutting edge 5 to the inside, namely, from the cutting edge 5 to the flat part 6.

  • the groove part 8 is configured to include a region where a groove width is largest in a top view (refer to the line A-A in Fig. 3 ).
  • the groove 8 is also configured to have the largest groove depth in the region where the groove width is largest, as shown in Figs. 4(a) and 4(b) .
  • the term "groove width” of the groove part denotes a distance in a direction orthogonal to the cutting edge in a top view, that is, a width of the groove part contributing to a chip curling action.
  • the term "groove depth” of the groove part denotes a maximum size of the groove part in a direction perpendicular to the upper surface in a cross section passing through a line perpendicular to the cutting edge in the top view.
  • the bottom portion 82 exits continuously along the major cutting edge 51, and a partial region of the bottom portion is preferably inclined (an inclined groove region) downward away from the minor cutting edge 53.
